Several data files are bundled with the specter package.  This document
summarizes these files.

Sky Data Files
~~~~~~~~~~~~~~

These files are used for building up input models and throughputs.

ZenExtinct-KPNO.fits
    HDU 1 has a binary table with columns ``WAVELENGTH`` [A] and ``EXTINCTION``
    [mag/airmass] for KPNO.  Below 5000 A the curve is from kpnoextinct.dat;
    above 5000 A is from Arjun Dey.  The data were merged by Nick
    Mostek for bbspecsim.

sky-uves.fits
    HDU 1 has a binary table with columns ``wavelength`` [Angstroms]
    and ``flux`` [1e-17 erg/s/cm^2/A/arcsec^2].  This is a sky spectrum from
    3400-10600 A (vacuum) stitched together from the individual spectra
    described and `available from ESO`_.
    The code that originally generated this file is in a separate product,
    bbspecsim/pro/sky/uves_sky.pro .

.. _`available from ESO`: http://www.eso.org/observing/dfo/quality/UVES/pipeline/sky_spectrum.html

specter/test/t/

This directory contains sample data files used for unit tests.
